Maybe the question is also of interest beyond
biblatex but here's the thing: I recently published my
biblatex style biblatex-fiwi and I'm always having trouble making sure that updates don't lead to unexpected behavior. For example, I just realized that my last update includes a stupid error where a colon is dropped at an important place. The colon was there in previous versions but since I wasn't careful enough it's gone at the moment.
What I would like to have is some kind of automated testing environment which would check a set of bibliographic entries against a defined outcome. At the moment I always have to check the final PDF myself which is error-prone.
What's to easiest way to do this?
